Roof Small format products FX.12 roof panel Fastening

Fastening

  • Fasten each panel with the supplied PREFA 2.8/25 grooved nails (Fig 3). For PREFA coverings over thicker layers of bitumen, you will need longer grooved nails, such as 2.8/40. Please state this separately when ordering.
  • In areas particularly prone to storms, a wind load calculation is required and fastenings must be adjusted according to the calculation.

Standard fastening

  • FX.12 large panel: 5 pc. Ring shank nails
  • FX.12 small panel: 3 pc. Ring shank nails

Note

In the case of additional fastenings, the prepared grains can be used.

When installing FX.12, a minimum offset of 220 mm must be observed.
